Energy meter accuracy selection in different scenarios

‌The accuracy of energy meters in different scenarios should be determined according to specific needs. The following are some suggestions for selecting energy meter accuracy in common scenarios‌:

I.Household users‌: For ordinary household users, choosing a Class 1 meter (with an error range of ±1%) is sufficient to meet the needs of daily electricity metering. This meter is both affordable and can meet the needs of most households.

II. Industrial and commercial users‌:

1. High-end industrial users‌: For occasions such as semiconductor wafer factories that require extremely high accuracy in electricity metering, a Class 0.2S meter (with an error range of ±0.2%) should be selected to ensure high-precision electricity metering‌.

2. Conventional commercial scenarios‌: For large supermarkets and charging stations, you can choose a Class 1 meter, which performs well in the face of instantaneous power fluctuations and is suitable for commercial applications‌.
